Configuring Management Rules

notifications and take appropriate action. For details on developing a custom MBean and deploying it, see Chapter 14, “Developing Custom MBeans,” in Sun GlassFish Enterprise Server 2.1 Developer’s Guide.

The Enterprise Server provides some useful events, which you can further extend by writing custom MBeans to emit notifications. Each event can be further customized by changing its properties.

The following event types are available:

■Monitor events: Monitors an attribute of an MBean. Monitor events have similar capabilities to javax.management.monitor package capabilities. In addition to monitoring simple attributes, as Java SE 5 javax.management.monitor does, monitor events also support monitoring complex attributes.

■Notification events: Notifies of events from a custom MBean. Use these events to write custom events and thus extend the event dictionary. Any MBeans which can emit a notification can be an event.

■System events:

■Lifecycle: Events for sever startup, showdown, and termination.

■Log: Events triggered when the specified logger writes a log entry. For example, you could create a management rule to send an alert to an administrator when an EJB container logger logs a SEVERE log entry.

■Timer: Events triggered at the specified date and time, at the specified interval, and so on. These events have capabilities similar to the javax.management.timer package.

■Trace: Events triggered on Entry and Exit of HTTP/IIOP request methods, EJB methods, and Web methods. For example, you can design a servlet filter used to log interactions with a servlet as a management rule using Web method Entry and Exit events.

■Cluster: Events triggered when a cluster or instance starts, stops, or fails. These events use the Group Management System cluster monitoring.

Configuring Management Rules

To configure management rules in the Admin Console:

■In the developer profile, go to Configuration→ Management Rules

■In the cluster and enterprise profiles, go to Configurations→ Configuration → Management Rules

Note – On this page, check All Rules Enabled to enable management rules globally. If management rules are not enabled globally, none of the management rules are executed.
